Did this not used to include the relevant changlog entry?

Anyway, this is a change which I've just independently discovered is
broken and I'm investigating:

        commit a8a1f236a2964506a22d1779648d8e1c8668cb1a
        Author: David Scott <dave.scott@xxxxxxxxxxxxx>
        Date:   Tue Apr 23 10:59:26 2013 +0100
        
            libxl: Only call stat() when adding a disk if we expect a device to 
exist.
            
            We consider calling stat() a helpful error check in the following
            circumstances only:
             1. the disk backend type must be PHYsical
             2. the disk backend domain must be the same as the running libxl
                code (ie LIBXL_TOOLSTACK_DOMID)
             3. there must not be a hotplug script because this would imply that
                the device won't be created until after the hotplug script has
                run.
            
            With this fix, it is possible to use qemu's built-in block drivers
            such as ceph/rbd, with a xl config disk spec like this:
            
            disk=[ 
'backendtype=qdisk,format=raw,vdev=hda,access=rw,target=rbd:rbd/ubun
